Jessie J showed her pipes are Pitch Perfect when she sang the signature song for the PP2 soundtrack…
AND we know she's capable of cranking out crazy hits (we still can't get Bang Bang out of our heads).
But, if you think these excellent examples of pop prowess are new to the British beauty, think again! Not only did Jessie write Miley Cyrus' jam Party in the USA, but she's been flaunting her ridiculous riffs and brilliant belting for years!
Not too long ago, the 27-year-old was sharing her incredible voice with the world by uploading webcam videos to YouTube.
Ch-ch-check out some of her best performances in honor of Flashback Friday (below)!
